Manuals from about 2021 onward name DOT-4 and give the standard 'SAE J1704 DOT-4 LV, ISO4925 CLASS-6, FMVSS 116 DOT-4'. Older US manuals (to about 2019: Optima, Sportage, Cadenza, Sedona, Stinger, Forte, Elantra GT, Genesis sedan, G70) say 'FMVSS116 DOT-3 or DOT-4'; the 2022/2024 Soul manuals say 'SAE J1703, FMVSS116 DOT-3 or DOT-4'. DOT 4 satisfies every edition.

Engine oil

API SN PLUS / SP or ILSAC GF-6 · 0W-30(2026 on · Palisade Hybrid (2026), Telluride Hybrid (2027))

Manufacturer-publishedSource

Full synthetic required: with a lower-grade (mineral or semi-synthetic) oil the manual says to change oil and filter on the severe-service schedule.

Oil capacity

6.13 quarts (5.8 liters)

Manufacturer-publishedSource

6.13 US qt (5.8 L). The manual's engine-oil row (labelled 'drain and refill' in most editions) does not say whether the figure includes the oil filter, so it is recorded as unspecified, not with-filter.

Coolant

Hyundai/Kia/Genesis ethylene-glycol coolant for aluminum radiators (phosphate-based), mixed with (distilled) water

Manufacturer-publishedSource

US manual wording varies by model and year: 'Mixture of antifreeze and water (Phosphate-based Ethylene glycol coolant for aluminum radiator)' (most Hyundai/Genesis); 'Ethylene glycol base coolant for aluminum radiator' (e.g. Sonata 2021-2027, Tucson 2025, Santa Fe 2024-2026, Sorento 2021-2022, Telluride 2022, Stinger, Cadenza); 'Ethylene-glycol with phosphate based coolant for cooling device' (Optima/Sportage 2017-2019, Forte 2019); 'A Phosphate based ethylene glycol based coolant' (Kia 2023 onwards). Kia manuals add: 'Different type of coolant or water may damage the electrical component.' Capacity varies by engine and model (about 6-13 US qt).
